British markings

[balsadust]

Hi everyone
I am from the US and was wondering if anyone can answer a question for me.
I have noticed through the years aircraft with yellow wing bottoms with black stripes.
Is this a designation for something?
I would like to build a large scale Waco CG-4A. I saw a picture of a a Hadrian with the yellow wing bottoms and thought that would be a good high visibility scheme.

Thanks in advance
Greg

It sounds like you're describing target towing tugs as shown by Canberra's etc. It was done for visibility to prevent the tug being shot at! ;D
